KONRAD MEIER, OF WINTERTHUR, SWITZERLAND.

RADIATOR.

Application filed Februaiy 2, 1916.

To all whom it may concern:

Be it known that I, Koiinan MEIER, a citizen of the United States of America, residing at l/Vinterthur, Tachlisbrunnenstrasse 12, Switzerland, have invented certain new and useful Improvements in Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which is appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to improvements in sectional radiators for direct heating in connection with a hot water or steam heating plant.

The object of the present invention is an improvement of sectional radiators. for di. rect heating, whereby the front facing the room is designed to favor the emission of radiant heat, while the back turned against the wall is formed to increase the heat emis sion by convection, that is, by contact with the air, which will carry it to the room. This improvement is accomplished by the simple means of depressions or grooves in front and rear of the individual radiatorsection or columns of oval or other typical oblong cross section, whereby the structural depth of the radiator is considerably re duced and at the same time the front surface facing the room, which freely radiates the heat, as well as that of the rear face, which serves mainly for heating air, is increased, while the ratio of the less eflicient sides facing each other to the total heating area is reduced.

The differentiated action of front and rear faces is accentuated or increased by making the depression or groove in the front face of less extent than that in the rear face which may be deepened to good advantage. so that the emission of radiant heat toward the front is still more preponderant and the air-heating at the rear face is further increased by the greater capacity for air circulation and the additional heating surface presented by the deeper grooves. The ideal and characteristic radiator for this purpose is a column or section having a cross section in the shape of an egg with inverted ends, the pointed end making a deeper depression than the flat end.

Specification of Letters Patent.

Patented Jan. 27, 1920.

Serial No. 75,710.

In the accompanying drawings are shown, by way of example, some modifications of the improved radiator, and it represents:

Figure l a diagrammatic plan of'two radiator columns, having a cross section of egg shape with both ends inverted, according to the first modification, the pointed end forming a deeper groove than the flat end, this being a general characteristic of the invention.

Fig. 2 a front View of a modified form.

Fig. 3 a side view of the same, showing two radiators set up together.

'Fig. 4 a fragmentary plan of two radiators according to a second modification, placed to act together, the left part showing a two-row radiator, the right part a single-row radiator.

Fig. 5 a plan, partly in section on line I-l of Fig. 2 on an enlarged scale.

Fig. 6 a cross section through a member, having corrugated side faces.

In Fig. 1 the single-row sections or columns M of essentially egg-shaped cross section have their front and rear faces de pressed so as to form grooves or troughs A and B respectively. Such a radiator member offers the same heating surfaces. as is offered by the full egg shape, while its width or the floor space needed is only :N, against N+N,+N, without the depressions or grooves.

The side surfaces of the several members or columns, which radiate heat toward one another, are obviously reduced, which, for the same total surface, improves the free radiation into space. The depression A, which is intended to face the wall, is advantageously carried farther than the front depression B, whereby the air-heating is greatlv enhanced.

In the modification according to Figs. 2-5, the individual columns or sections M are grouped in two rows and show an oblong oval cross section with convex sid'es C. The deeper troughs A here face each other and serve mainly for the air-heating purposes, while the more shallow troughs B for direct radiation face outwardly. The total heating surface of these columns M equals that of the old style columns with pointed or flat ends, having a greater width or floor space.

As is indicated in Fig. 5, the ratio of the freely radiating area OF to the total area EF is considerably greater for the new column with'dep're'ssions as compared with the old style, having longer sides, facing each other. 7

The inner ends of the two-row arrangement, when facing each other, form a channel or flue which induces better air circulation and therebyincreases the heating effeet.-

In Figs. f and 5 the air paths G are diagrammatically shown by full lines, and it is easily understood how the troughs A of the columns M thoroughly break up the air While giving ample area and an unobstructed passage, which makes for higher air velocity and greater heating effect than is obtained with theolder types of the two or more columns, with which the upper and lower headers generally obstruct the free circulation.

My improved radiator section thus offers over the old type the advantages of reduced space and considerable increase in heating capacity per unit of heating surface by reason of its peculiarity in having a greater ratio of prime radiating surface in front and a greater ratio of highly efficient contact surface in the rear, while the least efficient side surfaces facing each other are reduced. I

Obviously thedepressions A and B may be'of the same extent and the side faces may be corrugated, as shown in Fig. 6, to increase the heating'surface.

By providing'the depressions, the edges are doubled as compared with the old type member, which makes for a saving in material when using cast iron. These edges, being very short extensions, can be looked upon as prime heating surfaces.

Having now'particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is:

1; A sectional radiator for direct heating, whoselindividual columns are oval or egg shaped in cross section with inverted ends, the more pointed inverted end forming a deeper groove than the opposite blunter inverted end, the deeper grooves forming convectionchannels open at top and bottom, which channels are flanked by ribs, the shallower grooves forming radiation surface, thereby also obtaining a greater angle of radiation for the side surfaces of the columns.

2. An individual radiator column for clirect heating having a cross-section similar to the outline of an egg and having unequal ends inverted to gain space, to obtain a greater angle of radiation for the sides and to form cavities of different depth and proportions, the invertedblunt end being suited for effective radiation toward the front while the inverted pointed end forms a deeper cavity between sharper ridges or ribs allowing air circulation and air heating in the rear.

3. An individual radiator column for direct heating of oblong cross section having differentiated front and back faces, the front faces being moderately grooved surfaces developing high radiating efficiency, while the back faces are deeply grooved faces extended in the shape of ribs, utilizing the otherwise less efiective rear side for heating air by convection.

4. An individual radiator column for direct heating with distinctive front and back faces each having the shape of a groove, each groove being shallower in front for developing high radiating efficiency and deeper in the back for extending and utilizing the surfaces in the rear for heating air by convection.

5. A. column radiator whose individual columns are oval in cross section with inverted ends, the more pointed inverted end forming a deeper groove than the opposite flatter inverted end, the deeper grooves forming convection channels open at the top and bottom, and the shallower groove forming a radiation surface also open at the top and. bottom, thereby obtaining a greater angle of direct radiation for the curved sides of the column.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

KONRAD MEIAR.
